MANUFACTURING METHOD FOR METALLIC HOUSING OF ELECTRONIC DEVICE

摘要

A manufacturing method for a metallic housing of an electronic device is provided. The method includes providing a die-casting mold, including a male die and a female die engaging with the male die, the male die defining a pouring gate therein, and the female die defining a cavity therein corresponding to the pouring gate; positioning a metallic outer case in the cavity of the female die as an insert; assembling the male die to the female die to cover the cavity, thereby communicating the pouring gate with the cavity; casting pressured molten metal-alloy into the cavity via the pouring gate to form an inner structural member embedded in an inner side of the outer case; dissembling the male die from the female die to expose the cavity, and removing the outer case and the inner structural member from the female die.

1. A manufacturing method for a metallic housing of an electronic device comprising:
providing a die-casting mold comprising a male die and a female die engaging with the male die, the male die defining a pouring gate therein, and the female die defining a cavity therein corresponding to the pouring gate; positioning a metallic outer case in the cavity of the female die as an insert, the metallic outer case comprising a bottom plate, a peripheral sidewall extending from a periphery of the bottom plate toward a side thereof, and a plurality of latching hooks spaced from each other at an inner side of the bottom plate, the peripheral sidewall defining a receiving groove at an inner side along the peripheral sidewall; assembling the male die to the female die to cover the cavity, thereby communicating the pouring gate with the cavity; casting pressured molten metal-alloy into the cavity via the pouring gate to form an inner structural member embedded in an inner side of the outer case, the inner structural member comprising a protruding flange embedded in the receiving groove, and a plurality of combining grooves respective receiving the plurality of latching hooks; dissembling the male die from the female die to expose the cavity; and removing the outer case and the inner structural member from the female die.
